Class 12 Micro Economics - Chapter The Theory of the Firm under Perfect Competition NCERT Solutions | How are the total revenue of a firm, mar

What is the supply curve of a firm in the long run?

The market price of a good changes from Rs 5 to Rs 20. As a result, the quantity supplied by a firm increases by 15 units. The price elasticity of the firm’s supply curve is 0.5. Find the initial and final output levels of the firm.

A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?

How does the imposition of a unit tax affect the supply curve of a firm?

What is the relation between market price and average revenue of a price-taking firm?

What is the relation between market price and marginal revenue of a price-taking firm?

How does an increase in the number of firms in a market affect the market supply curve?

How does an increase in the price of an input affect the supply curve of a firm?

How does technological progress affect the supply curve of a firm?

Will a profit-maximising firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.

Explain the concept of a production function

What would be the shape of the demand curve so that the total revenue curve is?

(a) A positively sloped straight line passing through the origin?

(b) A horizontal line?

Explain market equilibrium.

Discuss the central problems of an economy.

What do you mean by the budget set of a consumer?

What do you mean by the production possibilities of an economy?

What is budget line?

Suppose a consumer’s preferences are monotonic. What can you say about her preference ranking over the bundles (10, 10), (10, 9) and (9, 9)?

What are the total fixed cost, total variable cost and total cost of a firm? How are they related?

How does the budget line change if the consumer’s income increases to Rs 40 but the prices remain unchanged?

What do you mean by substitutes? Give examples of two goods which are substitutes of each other.

Find out the maximum possible output for a firm with zero units of L and 10 units of K when its production function is Q = 5L = 2K. 

How is the equilibrium number of firms determined in a market where entry and exit is permitted?

How is the wage rate determined in a perfectly competitive labor market?

If duo poly behavior is one that is described by Cornet, the market demand curve is given by the equation q = 200 - 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price. 

What is the average product of an input? 

How are equilibrium price and quantity affected when income of the consumers

a) Increase

b) Decrease
